IMPROVEMENT m METALLIC CARTRIDGES.

Specification forming part of Letters PatentNo. 120,529, dated October 31, 1871.

To all whom it may concern:

Be it known that I, -ALWIN PAYNE, of Bridgeport, in the county of Fairfield and State of Connecticut, have invented a new and valuable Improvement in Cartridge-Shells; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this spec-. ification and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of a longitudinal section of unfinished cartridgeshell without the anvil. Fig. 2 is a longitudinal section of cartridge-case, showing anvil above re-eniorcement. Fig. Sis a longitudinal section of cartridge-case, showing anvil secured in place.

Fig. 4 is atop view of anvil; and Fig. 5 is aver tical section, showing the anvil and fulminatepocket.

This invention has relation to metalliccartridges; and it consists in the construction of the shell or case and the novel method of arranging and fastening the anvil or anvil re-enforce, as hereinafter described.

In the drawing, A represents the cylindrical shell or case of an unfinished cartridge, which 1- construct with an internal re-enforcem'ent, a,nea1 the butt or closed end a terminating in a shoulder, a. B represents the cartridge-anvil, or a reenforcement to the cartridgaanvil, of a circular or disk-shape, and formed with the cup b to hold fuhninatingpowder, or with perforations I) to let the spark from a cap pass through, and. with its periphery or rim beveled oii', as shown, for the purpose hereinafter described. I make this anvil of a size to fit closely within the, re-enforcement a, and having firstinserted a packing, a, of any suitablemateriahto preventthe escape of gas, I press the anvil down as closely as possible to the end of the cartridge-case, and then, by the use of a die and punch, depress the center of the butt a to make it conform to the shape of the anvil, and to thereby so re-enforce'it as to render it strong enough to withstand the percussion of the hammer. I next (or before having pressed the butt a take a cylindrical punching-chisel of a diameter equal to that of the cartridge-case beyond the re-enforcement, and drive it down into the case, causing it to separate the metal of the re-eniorcement, and to press it down over the edge of the anvil, so as to form a flange, I), which will hold the anvil securely'in its proper position.

In pressing down the metal to form this flange it swells so as to coincide and fit closely against the beveled periphery. of the anvil or anvil reenforcelnent B, thereby rendering it more firm andsecure. The external flange e of the case is formed at the same" time that the depression is made in the butt.

' I have above described a cartridge-case and anvil constructed according to the principles of my invention; but I do not wish to confine myself to any particular form of anvil, or other part not absolutely material to said invention.

. The chief elements of the invention are the reenforcement of the case and the'method of fast. ening the anvil,'or what may be termed a re-enforcement to the anvil, by pressing down. said reenibrccment so that it shall form a flange or guard to secure the anvil in place.

-What I claim as my invention, and desire to;

secure by Letters Patent, is-

1. The combination herein shown of. the re-en- 'forced shell A and disk or anvil B, whereby said disk or anvil-is firmly secured in place by upsetting or turning'the metal of the case over the disk or anvil, substantially as specified.

2. The improved cartridgeshell, having the flange b to hold the anvil or anvil-re-enibrcement .B, when said flange is formed from the menforcement a, for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

Witnesses: ALWIN PAYNE.-
